' INVENTOR. Anthony G. Rosa. 7 /6 ATTORNEY- United States Patent LOCKINGDEVICES Anthony G. Rosa, Lyndhurst, N. J. Application July 9, 1956,Serial No. 596,545

2 Claims. (Cl. 120--9) This invention relates to locking devices, and ithas for its purpose to provide a screw cap locking device that willsecurely prevent any detachment of an article secured, for instance, bya chain to an object, such, for example, as in banks or post ofliceswhere a penholder is chained to a table.

While the above illustrates one use of the device, the latter may findapplication in many various connections.

In the following description, wherein similar reference charactersindicate corresponding parts:

Figure 1 is a transverse vertical section of my device;

Figure 2 is a section on line 2-2 in Figure 1;

Figure 3 is a section on line 3-3 in Figure 1;

Figure 4 is a transverse section, with part broken off, showing amodification of my device; While Figure 5 is a view similar to Figure 4illustrating a completed operation of the device as commenced in Figure4.

Referring more particularly to the drawing, the numeral indicates abarrel and 11 a screw cap threaded upon said barrel, as shown at 15.

A cartridge 12 is disposed in said barrel; said cartridge is made with afew enlargements or humps 13 formed upon the side thereof.

The screw cap 11 has a transverse portion 14 or flute bushing formedintegral therewith, or inserted therein; said portion has a cut-out orsocket 16 in its lower part adapted to seat an enlargement 13 of thecartridge.

The barrel 10 has in its upper part arranged a similarly transverseportion 17 formed with a central opening 18 of a shape so as to permitan enlargement 13 of the cartridge to pass up and down therein.

A coil spring 19 is mounted upon the lower part of the cartridge andrestricted in its expansion by the enlargement 13 and shoulder 20 in thebarrel; while space 21 is left in said barrel to permit movement of theball point tip 22 of the pen.

A ball chain 23 has a detachable sleeve 24 secured between two balls andheld in place by the shoulder 25 of the cap.

In order to remove the ball chain and sleeve it is necessary to presssaid sleeve 24 downwardly against the upper end of the cartridge 12,whereby the upper enlargement 13 will become disengaged from the socket16 and "ice assume a position approximately as indicated by 13 in dottedlines; while simultaneously the next to the upper enlargement will alsomove downwardly as shown at 13' in dotted lines.

By thus extricating the upper enlargement 13' from said socket, it ispossible to unscrew the cap 11, thus permitting the separation of thecap from the barrel and cartridge.

In Figures 4 and 5 is shown a modification as to the operation of thedevice, while the principle as to releasing the cap from the barrel issubstantially the same.

Thus in Figure 4 the cap 11' is formed with a through opening 27, whichpermits the insertion of a pin 28 or the like,'by means of which thecartridge 12', that in this instance is shorter, is pressed downwardlyso as to release the enlargement 13" from the socket 16', as may be seenin Figure 5.

I claim as my invention:

1. A screw cap locking device comprising a barrel, a cartridge mountedin the latter, humps formed on the sides of the cartridge, a capscrewthreaded upon said barrel, an enlargement within the barrel, saidenlargement having a transversely extending opening therein for thepassage of the cartridge, another enlargement within the cap, saidenlargement being formed with an opening therethrough and a transversesocket at its lower end adapted to seat a hump laterally extensiblethereinto, whereby, when said bumps are therein relative rotationbetween the cap and barrel is prevented, the cap having an opening atits top, a shoulder surrounding said opening, a sleeve mounted in thelatter and being retained therein by said shoulder, said sleeve beingadapted to actuate the cartridge in a downward direction to disengagethe said hump from said socket, whereby to permit the unscrewing of thecap from the barrel.

2. A screw cap locking device comprising a barrel, a cartridge mountedin the latter, humps formed on the sides of the cartridge, a capscrewthreaded upon said barrel, a transversely extending enlargementwithin the barrel, said enlargement having an opening therein for thepassage of the cartridge, another enlargement within the cap, saidenlargement being formed with an opening therethrough and a transversesocket at its lower end adapted to seat a hump laterally extensiblethereinto, whereby, when said humps are therein relative rotationbetween the cap and barrel is prevented, the cap having an opening atits top, a shoulder surrounding said opening, a ball chain, a sleevemounted between two balls of said chain and being retained by saidshoulder, one of said balls actuating the cartridge in a downwarddirection, whereby to disengage the hump from said socket and permit theunscrewing of the cap from the barrel.
